This invention relates in general to the art of batik and specifically to tools for applying wax or other protective substance to articles to be batiked or to materials to be etched.

5 The devices now in use for this purpose are crude and ineflective and consist as far as the applicant is aware of the ordinary brush; the Japanese ty'antz'ng which is a spoon shaped ladle provided with a small outlet tube, and the batik pencil which is a device quite similar to the ordinary stylo raphic pen. These devices are subject to c ogginlg due to the cooling of the wax. The brus method cannot produce either even waxing or lines of uniform width. It is also very diflicult to carry suflicient wax for a line of appreciable length without the'wax dripping from the brush as it is brought over the article.

so In the tjantz'ng no means is provided for controlling the flow of wax and the line width will vary with the temperature of the wax. Also regardless of how adept the artist may be, it is impossible to move from one figure to .the next without depositing drops of wax where not desired. This device and also the ordinary brush are depend ent upon an open source of heated wax which is not only disagree-able but also dangerous so owing to the fire hazard, and liabilit of burns etc., thru spilling or spattering o the hot wax.

The batik pencil leaves much to be desired.

In this device the flow of wax is controlled by pressure upon the needle point. Wax drops frequently form on the needle causing imperfect work. It is also diflicult to produce lines of even width owing to the method of flow control. This device is also subject to clogging and sticking due to solid particles in the wax lodging between the needle and the tool body thus producing either failure to flow or more serious, unexpected failure to shut off the wax. This device and also the tjantz'ng require frequent heating which in practice is accomplished by the use of an alcohol lamp.

The object of this invention is to produce a new and improved tool which will obviate these deficiencies and produce fine even lines under absolute control and of constant netration so much desired in batik and etc ling.

Other objects and advantages of the present invention will become apparent from the following specification, claims and appended drawings in which:

Fig. 1 is a perspective view showing the device of my invention showing a method of using the same.

Fig. 2 is a front elevation of my device.

Fig. 3 is a sectional view on the line 33 of Fig. 2.

Fig. 4.- is a top plan view with part of the handle broken away.

Fig. 5 is a detail sectional view showing in enlarged scale the interior construction of the tool point and needle valve.

Fig. 6 is a sectional view on the line 66 of Fig. 7 is a sectional view on the line 77 of fieferring to the drawings, the body of the tool consists of an inverted hollow cone designated by the numeral 1 which is adapted to contain a quantity of wax. A cap 2 closes the base of the cone and is removably secured thereto by bagonet slot or other suitable connections. handle or hand grip 3 is provided and will be more fully described hereinafter. The body of the cone is formed of brass or other suitable high heat conductive material while the apex of the cone is of a strong wear-resisting material such as steel. This apex portion is designated by the numeral 4. As shown in Figs. 3 and 5, the apex portion or ti is formed with an aperture 5 extending su stantially axially of the cone and providing a channel between the interior of the cone and the extreme point thereof. The aperture is of conical shape as it approaches the point thus permitting the tool to be constructed with a very fine point, which keeps its shape owing to the use of the harder material, i. e. steel or the like.

The cap 2 is provided with an aperture 6 in line with the aperture 5 and a controllin needle 7 extends thru the aperture 6, through the recess of the cone 1, and into the aperture 5. A manually operable lever 8 is pivoted in a block 9 secured to the cap 2 and one end extends thru and closely fits within an opening in the needle 7 as shown in Figs. 3 and 4. The other end of this extends adjacent to the handle 3 Where it is provided with a thumb or finger piece 10 whereby the lever maybe" manipulated by the operator and the needle 7 raised. A spring 11 normally biases the needle 7 to close the aperture 5 in the tip 4. This spring is mounted on a block 12 secured to the cap 2.

The construction of the needle point forms an important part of my invention. As will be seen in Fig. 5 the needle 7 extends, whep in closed position, substantially flush withthe end of the tip member 4. It will also be seen that a very short distance from the lower extremity of the latter, the needle is cut away or restricted in a conical manner 14 and that from this restricted portion 14 the needle assumes a polygonal form 15 to a point well within the body of the wax reservoir. By this construction, the wax is shut off at the point of discharge, yet upon raising the needle only slightly a full and even flow is permitted. Upon quick closing, excess wax is not forced out of the end of the tip 4 but may pass up thru the restricted portion 14 and the polygonal portion 15 of the needle 7 into the body or reservoir portion 1 of the tool. An absolute control of the flow of wax is thus obtained.

The tip member 4 may be secured to the body 1 in any manner as by screw threads. The tip arches slightly within the hollow portion of the body 1 and thus forms a peripheral groove or channel 16. Solid or hard particles in the wax collect in this groove 16 and are thus prevented from passing down along the needles 7 within the aperture 5 of the tip 4.

Another very important feature of my invention is the special manner of application of heat to the tool, whereby the wax may be maintained at an even and constant tempera ture as long as desired and without any interruption of the work. To this end, in the embodiment shown by way of example in the drawings, an electric heater 17 is attached to the body of the tool.

As clearly shown in Fig. 3, the heating unit 17 is inserted within a tube 18 brazed or otherwise secured to the side of the body or reservoir 1. The upper end of the tube 18 is closed by a removable cap or plug 18' thus facilitating the assembling of the device. The lower end of the tube 18 is provided with an outwardly projectinc portion 19 to which the handle 3 is secured. The handle 3 is of hollow construction and is provided in the outer end thereof with means 20 for connection to a source of electricity. From the connecting means 20 to the heater unit 17 appropriate wiring connections 21 are provided within the handle 3 and .a suitable switch 22 is convenlently mounted in the handle whereby the operator may open and close the circuit at will.

In the drawings I have shown a thermostatic switch 23 mounted adjacent to the body 1 in a downward extension of the tube 18. An adjusting screw 24 allows regulation of this thermostatic control. As is clearly shown in Fig. 3, the thermostatic switch is readily removable and replaceable and if desired, may be dispensed with and a suitable plug provided for insertion within the tube 18 to complete the electric circuit. Of course, if desired the device may be built without provision for the thermostatic switch.

A thermometer 25 is secured to the body 1 in such a position that it may be easily read by the operator. This thermometer is for the purpose of indicating the temperature of the reservoir body and therefore of the contents of the same. The operator is thus always cognizant of the condition within the tool and may adjust the thermostatic control or operate the switch 22 as conditions require.

A filler opening 26 is provided in the cap 2 through which the tool may be filled. This opening is closed by a cover 27 pivoted on the cap 2. A small aperture or breather opening 28 is made through the cover 27 in order to allow for the expansion and escape of gases from within the tool. The cover 27 may also be made of spring material of sufficient strength to normally keep the opening closed but yielding under abnormal pressure from within the tool.

The operation of the device is substantially as follows:

Wax is introduced into the reservoir thru the opening 26 or by removing the cap 2. The wax may be in the convenient stick form of commerce or in any other suitable form. The connecting means 20 is connected to a source of electricity, switch 22 is turned on and the heating unit 17 receives current and starts to heat the tool 1 and the material contained in the same. The needle valve 7 is meanwhile kept closed by the spring 11. When the wax has become melted and sufficiently hot, as determined by consulting the thermometer 25, the operator grasps the handle as shown in Fig. 1 and puts the tool in the correct position over the work. To let the wax flow on the work and form a line, the thumb rest 10 is pushed down, raising the needle 7 by means of the lever 8, so as to open the orifice 5, and the tool is moved along the work, depositing the liquid wax in a thin uniform line. Since the heat is still supplied to the tool, the wax is kept liquid and the work need be interrupted only when the tool must be refilled with wax. In case the wax becomes too hot, as shown by the thermometer, the switch 22 can be turned off or the thermostatic device 23 may be set at the proper heat by adjusting screw 24, and operate to cut oil the current to the heating unit 17, to maintain an approximately constant operating temperature. The

- this ing tip, which tip is formed flow of wax can be cut oil by simply releasing the thumb rest 10.

This tool 1 can be manipulated with great accuracy since the cone shape gives the operator an unobstructed View of the point of the tool during operation. There is no danger of dripping from the end because the needle closes the opening at the extreme tip of the tool, and excess wax in the orifice passes back through the recess formed by the polygonal section to the reservoir of the tool. The needle cannot become wedged in the open position by hardv particles, because the latter are caught in the groove at the junction of the body 1 and the tip 4 and do not enter the orifice 5. Since the flow is uniform, there are no unintentional interruptions of the wax line on the work and therefore much loss of valuable material due to running of the color is avoided. The constant temperature of the wax produces even and thorough penetration heretofore impossible to obtain.

There is no danger of the tip or the needle catching in the material even through it may be of the very finest, since the edges of the tip are rounded off, inside and out, and the needle does not protrude at all beyond the lower extremity of the tip.

The term wax is used broadly throughout application and is intended to apply to all materials used for the same purpose.

Various changes in the construction of the embodiment illustrated in the drawings may be made without departing from thespirit of the invention, and I do not therefore desire to limit myself to the specific construction shown and described but to interpret the invention broadly within the scope of the appended claims.
